Is there a way to see if Shield triggers the second HEVC stream with dual-layer DV files with the developer menu or command line?
Second stream in dual track file will not play.
As for second stream (layer) merged in single track...
There is no way to tell for sure is FEL active or not. No test patterns exist, no reports in logs.
Only visual observation.
Based on theory visual difference could be in
a) smoother gradients
b) less compression artefacts in shadows (mostly in red and blue tones)
c) overall cleaner image with less shimmering
Keep in mind - if video has high quality properly encoded HDR base layer than FEL layer improvements are less and less noticeable, neglectable, or almost none. Indeed 2bit more data is here but probably it should be seen on true 12bit panel to spot something.
So If FEL discarded than image in HDR should be identical to DV Base layer plus some difference in contrast because of tonemapping.
I spend hours and hours to find any difference between HDR and DV and Shield . Heck, I even bought X700 solely for FEL-noFEL comparison purpose
One particular scene with oblivious difference I've found is Valerian 00:52:40 mark - better blue gradients

I don't not say FEL is fully utilized and don't say FEL discarded. But after hours of testing I don't really care about FEL anymore until proper test patterns appear.
Red push and blocking is real problem for now
