It's still not fixed in AE 17.5.1 and AE Beta 17.6.0 (Build 25) on Windows 10 v.2004 64 bit.
I can't say anything about the Mac version because I don't have one and I can't test it.
After extensive tests by looking at the actual RGB color values and not only judging by eye if there is banding or not I have to disagree with Ярослав Семенов.
This is NOT only a GUI bug at least not on windows!There is definitely a loss of color depth information!
This is a footage interpretation bug and not only a GUI bug.
There is also another footage interpretation bug for Prores4444 files when Alpha Channel is Premultiplied. After unpremultiplication (interpret footage) the unpremultiplied RGB values are wrong.

Tested today 17.5.1 on Mac*.
Gradient rendered in Trillions - appearing as Millions in Project panel, but it has no banding (compared with file rendered in Millions).
So it's seems to be just GUI bug.
* Tested on Windows too, but without comparing files.

Still happening in 17.5.0
This is NOT the case:
"- Rendering with "Millions of Colors (8bit)" Data Rate and file size is higher then with "Trillions of Colors (16bit)"! Should be the opposite!!!"What's happening is the Millions setting applies 8-bit dithering, which in turn makes the compression less efficient, and so the file size is larger.
Actually, the Trillions exports work. They look good in other applications. It's just AE that reads them in as 8-bit.

I confirm this bug!
Bug exists on Wondows too!
AE 17.1.4 (Build37)ProRes 4444 has many more bugs and it's totally broken in AE 17.1.4:
- Rendering with RGB+Alpha with "Alpha Premultiplied" results in wrong Alpha Channel
- Rendering with "Millions of Colors (8bit)" Data Rate and file size is higher then with "Trillions of Colors (16bit)"! Should be the opposite!!!Adobe fix this **** I need to work!

All imported Prores 4444 files are interpreted as 8-bit (Millions).
A gradient ramp, exported as Prores 4444, rendered at Trillions, will read correctly in Premiere, Flame, Nuke etc. But the same file in After Effects is shown as "Millions of Colors" and shows banding.
ProreHQ files do not have this issue.
