Unfortunately, BDP-203 is going to be missing many features that 103 offers when it comes out. Hopefully, it will be updated to where 103 is today.
Things may be a little messier than you think.
To receive a Netflix 4K stream you need a device which is 4K such as your TV, and if you're using an app then that app has to be written to accept 4K. Mu understanding is that Netflix write all of the Netflix apps you see on players and TVs, and they write them for whatever operating system the device is running plus I think the app "tells" the Netflix server what resolution it can send, whether or not the device can accept HDR, and what sort of HDR encoding it can accept.
I've got a 105, an LG E6 display, and the Samsung UHD player which I bought as a temporary measure for playing UHD discs until the 203 is released. All have Netflix apps. Like your 103, my 105 only accepts 1080p input so 4K offerings do not get listed. The Samsung is a 4K device and it displays 4K offerings but it doesn't display any of the Dolby Vision HDR encoded offerings Netflix has because the Samsung player is not DV capable so it shows just the SDR 4K versions. The E6 is 4K and can handle Dolby Vision so it lets me access the DV encoded 4K versions but I run into problems with lip sync and audio formats at times so I ended up buying a Chromecast Ultra which is 4K and can accept both HDR10 and Dolby Vision HDR encodings and I can get the best audio from it. I connect it directly to my AVR. I don't know if Netflix has any 4K content with HDR10 encoding but I'm in Australia and they have a smaller range of offerings here. The only HDR encoded content I've come across on Netflix so far has all been DV encoded.
So your best bet until the 203 gets some of the hoped for feature improvements such as streaming apps from Netflix and other providers and Dolby Vision capability is some sort of streaming device such as the Chromecast Ultra which works quite well. You won't be able to connect it to one of your 103's HDMI inputs for video processing because they don't accept 4K, you'll need to connect it to a 4K capable AVR or one of your TV's HDMI inputs, but you will be able to connect it to the HDMI input on the 203 if you get one.
So that is really your options at the moment: use the TV app or get something like the Chromecast Ultra.
If all that is worrying you is not being able to get DD+ audio, check out what your TV can pass to your AVR via the audio return channel. You may be able to get DD+ audio to your receiver that way.
