Here's another thing that baffles me as well. From what they have shown, they are upscaling the Menus and UI all the same as everything else.
Yet, Code Veronica X HD, a game that predates REmake, got a completely re-drawn proper UI/Menu system.
And with basically minimal effort, a consumer like Alo81 can simply upscale and make backgrounds look nearly the same as Capcom themselves, and add post processing without crushing detail.
This is akin to, recording and mixing a song in 24-bit 44.1khz .wav, using only a 16-bit 32.khz 92kbs .OGG for shipping said music due to limitations in an old retail game.
Then later releasing a musical album of "Remastered" music from said game in 16-Bit 44.1khz FLAC, but all of the audio is simply upsampled from the old retail game files.
