Absolutely! It just looks professional when you don’t have viewport hanging edges. Definitely do this.
If their primary color is black, use subtle pastels to create more character. Try not to use definitive absolute colors, if you know what I mean. Deep solid blues, greens, reds, etc. Instead use lighter variations:
You can use these lighter variations as “Character, Highlights, Subtle, Accessories”. This wouldn’t be changing their color scheme, it just adds to the flavor. You can see where the arrows are pointing. Choose subtle tints on the 3rd or 4th row. The first three are those absolute colors I was referring to. Refrain from using those first two deep, deep color rows, they’re way to imposing and drown out text and personality.
Shadows allow the eyes to smoothly read much better. It takes user away from the Excel spreadsheet looking grids. You want these grids & blocks to float on the page, not implanted. Add subtle shadows throughout and let the “Text” do the talking. Here’s where you can use these “Pastels on text sitting inside a white/grey shadowed box”. The text with character, not the grid.
Use placeholders. When a team member is missing add something like this:

Use a vector background and fade it out, then put “Text or Branding on top”
