I already did today's dordle and haven't found a way to go back to view it.  It just shows my results. I can take a screenshot tomorrow.  When I go to free dordle I can see that the letters are grayed out.  But not for daily dordle. Unless it's something to do with dark mode but I have tried turning my brightness up and switching it from dark mode so I don't know.  

I'll post a picture tomorrow unless you can tell me how to view the one I already did.  

Thanks.  

It seems that it might have something to do with the setting that darkens the phone to a black screen at sunset.  I usually do dordle before the sun comes up but here is today's and you can see that the letters are grayed out.  

I also posted another where you can see that the screen does not show that. 

I put this picture down lower since it is today's dordle.
