Yea, this looks even more fake, definitely can't say this could be real without seeing the game exe now.
That video doesn't show anything that can't be faked. It does show a lot of inconsistencies tho.
For it to be a build from when the ClockTranslucentTable(sidebar clock tint, sub cloak color) was blue the radar doesn't match. The radar had a blue outline signifying the bounds of the UI element, i guess for gadget debugging purpose, that code still exists in RA. You can see it here, You can confirm this screenshot is of that era looking at the missiles the subs fire which aren't brown but blue and by examining the last indexes of the palette.
Notice also in the screenshot there's no radar art behind the radar, only black, the art didn't exist in these builds.
The Help Text(simply(but factually wrongly) put, on cameo tooltips) used to remap to the house, so red for soviets blue for allies, i recently found that code in RA.
