Grout stained mosaic tile

Greetings, My name is Jeff. I have been a long time user of the forum and it has helped me through 3 different bath remodels. I have tried something new for my last project: charcoal sanded grout with 1" Hex mosaic porcelain tile. The tile color is biscuit, which is essentially a less-white white. Knowing that the tile color and the grout are very different, i put 2 coats of sealer on the tile to prevent any staining. However, that seems to have not done the job, because now the tile has a bit of "gray" color. It is not haze. I have tried vinegar and water, and "grout cleaner" and have had no luck. Any ideas on what could possibly help clean the tile while not changing the color of the grout itself?

Could this just be a color illusion caused by the black and biscuit colors together and/ or lighting?

Sealer left on tile? Don't know if a stripper would affect the grout though.

Maybe Royce is right,the sealer may have changed the look.The tile should not have absorbed the sealer and it sat on top and needs to be stripped.if the tile did absorb the sealer it is porous and probably absorbed pigment also,very hard to get this out,you'll have to experiment with a haze remover after stripper, or some Barkeepers friend might work, but be careful it has oxalic acid and may etch the grout,flood the grout with water before attempting, and just do a couple tiles as a test.
