have you tried a pc running itunes for downloading itunes purchases?

Yes. I used Itunes on Windows with it set as "Download Full-sized HD" and "Download High-Quality SD Videos". I would download to PC, then use DVDFab DRM Remover on them. (back when you could still use older versions of iTunes with DRM Remover which allowed it to worked. DVDFab DRM remover still works on audio, as well as videos that do NOT require the latest version of iTunes)
Audio on the iTunes movies were always 128kb/s 48kHz AAC-LC 2 channel and 384kb/s 48kHz AC-3 (DD) 6 Channel. While for Amazon I get up to 640kb/s 48kHz EAC-3 6 Channel, rarely stereo. Its not just the higher bit rates, but EAC3 is better than AC3 too.
Video bitrates on iTunes downloads were always between 4000 kb/s and 5000 kb/s. (a most were at/near 4500kb/s) AVC/H264.
For Amazon, the video bit rates do vary a lot depending on content. Add StreamFab can download from Amazon as H265, so while H265 can/will have lower bitrates, H265 is more efficent so it can use a lower bit rate, and save space, yet achieve the same and better video quality.
Compare Aquaman from iTunes (BEFORE running it through Fab DRM Remover, however after using DRM remover the specs were still the same)
First Video Stream:
5,091kb/s, 1920*1080 (16:9) at 23.976 FPS,
AVCFirst Audio: English, 160kb/s, 48 kHZ, 2 channels, AAC LC
Second Audio: English,
384 kb/s,
AC-3 6 channel
(Dolby Digital)Aquaman from Amazon (using StreamFab)
First Video Stream:
5,622 kb/s, 1920*1080 (16:9), at 23.976 FPS,
HEVCFirst Audio: English,
640 kb/s, 48 kHz, 6 Channels,
E-AC-3 (Dolby Digital Plus)in this case, the video bit rates of 5000 vs 5600 seems "close" but Amazon is using HEVC (iTunes is AVC which is H264) and still has a higher bit rate.
And as you can see the 6 channel audio is a lower bit rate and AC3 compared to the Amazon download.
