Yes. Philips TV is DVLA compatible.
Also I set up my Windows PC as a DVLA server and was able to see photos on the TV.
At the moment I've loaded a UPnP client onto Firestick and I can see photos stored in the NAS.
However that is access through wi-fi to Firestick and the TV is ethernet connected. I do't know if wi-fi would be slower than ethernet.
