Incorrect sRGB profile ?

[ceejayemm]

Following a recent update of my RPI4 4GB (sudo apt update / sudo apt full-upgrade) I then just happened to check on the NPVR Service to check it was running:

pi@CMTV2:/opt/nextpvr/system/data/scripts $ service nextpvr-server status

Are the 'libpng warning' messages anything I need to be concerned about ? If so what do I need to do to fix them ? 

I am running NPVR v5.0.8 and, as you can see, the system has been up continuously for quite a while (since v5.0.8 was released in September). I am not seeing any problems with its day to day use. I can provide the logs if necessary but on this occasion I am not sure they add anything.

Thanks
