If / when you get a 4K TV and a 4K BDP you can bypass the receiver anyway. Both the Samsung and the Panasonic 4K BDPs on the market now have dual HDMI sockets. One is fully functional for connecting directly to your TV (or receiver if it's 100% compatible with HDR, HDCP2.2, still believes in Father Christmas, etc.), and the second one is audio only for pushing, erm, audio only at receivers that don't support the aforementioned codecs yet. I expect other brands will follow suit if / when they release their own 4K BDPs.
If you're not going to get a 4K TV and / or BDP any time soon, there are quite a few modestly priced (especially secondhand) 1080p BDPs with dual HDMI sockets that will let you do the same thing.
