Hi Vorkapitan,
I don't know whether Vecko has modified any of the core-settings of Dynamic Environment during the making of TWoS. To stay on the safe side, I wouldn't advise you to enable DynEnv's main mod (containing the core files) on top of TWoS. Nonetheless, enabling most DynEnv's optional mods should be pretty okay.
Since you like clearer underwater, you can enable:
DynEnv v2.9 - 3.b Enhanced Visibility (high)
DynEnv v2.9 - No Underwater Impurity Patch
Note that there is just one "official" 'No Underwater Impurity Patch' (I noticed you got two of them).
The 'Camera Filters - Vivid Colors' submod might intefere with SteelViking's interior mod, also included in TWoS. You can enable it and see what happens or, even better, you can use Sjizzle's
Sweet FX for SH5 instead. There is a warmer tone-more saturated preset in the settings pack. You can enable it as you do with any other mod (just make sure to enable it on top of the main mod.
