Twitch vs YouTube with other then 16:9 aspect ratios

Seeing if Twitch does do re-scaling right... So, with YouTube if you're streaming a non 16:9 resolution (5:4 at 1280x1024 in my case): YouTube will downscale it to 720p (permanently!) and put (top and bottom) letterboxes in during the live stream... Twitch on the other hand does respect the aspect ratio you're sending to their ingest server... My best guess is that Twitch was forced into this mindset because of all the monitor sizes it had to support; While YouTube focused on common Camera aspect ratios (and defaulted to 16:9). Something that's no longer current going by the fact that mobile phone manufacturers don't respect the 16:9 aspect ratio (like for example the Nokia 7.2 that until recently "recorded video in a larger width size)....
