I have , but I'm currently at work - My day time water looks like your but that is because CDPR changed the water in 1.21 - But your night time water looks different , especially your first screenshot .... Something went wrong there.
An exit and load of the save resulted in the second screenshot appearance, so it may have been something temporary, however in all my screenshots (more than posted here) the water at night is still duller and has less contrast than it did before 1.20.
I don't have time to go in and take more (I can do that later on though), but here are a few screenshots that I took before today. They seem perfectly fine to me (and definitely not like yours). There is definitely something fishy going on there. It wasn't rainy though, I should mention that.
Thanks for the shots. Bit hard to tell since it's B&W rather than a comparable place in the base game but I do see reflections of the moon/sky like yours in the second shot but only at certain angles and times at night. For example here are two taken around Novigrad during a storm:
The waves are great but I've found in these conditions at night it's still plainer.
