Dolby Vision now possible through MP4 Mux.

It is really noticeable. iTunes P5 colors look washed out compared to HDR10 or P8, especially red and green.
P5 is just more efficient, and it has reshaping data like FEL, so the colors are improved (unless it's from Apple), but this is not something you would notice because it exceeds our 10-bit display.
P5 will always retain the original master brightness like FEL P7, so sometimes you get brighter HDR with P5. Last Breath is a recent example:

Bitrate never means much; the only way to verify encoding quality is a screenshot comparison. For example, Apple's 24mbps bitrate is way worse than Movies Anywhere's 24mbps bitrate.

So for ALL movies/TV shows from Apple/iTunes we should never download the DV Web files but prefer the HDR10 Web versions?

Disagree with that - bitrate always makes the image look noticeably sharper to me (even just in motion without having to screenshot), because of the more data, especially along lines or walls and hair and grass and stuff like that - especially now compared to some ~15Mbps HDR10 vs ~24Mbps DV5 encodes for the same title some places will pump out

Once I start getting to ~30Mbps+ HEVC I start having to freeze frame and pixel peep myself to notice any encoding differences (mainly with self encodes from UHD there cause I've only seen Sony put out ~75Mbps UHD disc level stuff with Bravia Core)

,
I guess you didn't compare or encode enough content because I'd take a 15mb/s encode from MAX, Disney or netflix over a 24mbps iTunes encode any day...
Some Bravia Core high bitrate encode are of worse quality than lower bitrate bluray remuxes.

bitrate means nothing if the encoding settings are bad or denoised like Apple does.

P8 HDR10 version yes. As long as the brightness matches.

2021 or older TVs should be fine...
try it:
cmv2.9 https://drive.google.com/file/d/1MJUTgY ... drive_link
cmv4.0 https://drive.google.com/file/d/1yU3wk6 ... drive_link

Yes. Both files play like they should on my Ugoos on LG G1. Thanks.

Lucky you !

Could you please also try the banding and black fade samples in HDR10 and DV, and see if you get the same as my C2?

Yes I did this also. But I didn't reply because I'm not seeing the same things. I don't see much (if any) difference in banding in these examples between hdr10 and dv.

I did see a small difference in the black fade examples though. But not horrible like you say.
I do have the setting "Smooth gradation" to low, maybe that makes a difference?

[RESET_9999]

yes, you have to disable smooth gradation. This setting removes fine details anyway.

HDR10:



DoVi

Will try it again with smooth gradation off when I'm back from work later tonight.

My god....i havent being on this page in a while....the scripter who made this first happen rocking hard i see....
im gonna need a update on whats being changed dam....

Did the comparison again with smooth gradation off but it doesn't change anything. I hardly see any difference between the HDR10 sample files and the Dovi ones.

Are you watching in a dark room?
Near black Posterization and banding on LG OLED TVs is a well-known issue, and many people have moved to QD-OLED Samsung because of that. My Samsung monitor and Hisense LED TV don't have any of those LG issues.

Yes I'm watching in a dark room. The sun was down for hours and there were no lights.
Guess I still got a good one from LG

I would never move to Samsung by the way. A company that doesn't support Dolby Vision can't take my money.
