The Polk Omni S6 manual says "DTS Play-Fi transmits high-resolution files, but it does down-sample them so that they can be distributed throughout a home." What? I found a Crutchfield review of the Definitive which says it down-samples 96/24 to 48/16, i.e., maybe that's the max you can transmit over Play-Fi ?
Also, the Polk Omni A1 is the only reasonably priced stand-alone amp ($200) whereas Denon, Paradigm and Definitive's are $500, which is more than their smaller speaker/amp combos. Probably, they're assuming that if you want to use your own speakers then you're not interested in saving money.
The Samsung R5/R7 play high-def FLAC, as does the LG Music Flow H7. But I doubt their speakers are very 'high def', both because of the brands and also because of the low prices, e.g. $300 vs $500-800. But the LG has a nice rotary volume knob :-)
Finally, I haven't seen any mention of DLNA renderers so probably none of these will work with my existing BubbleUPnP app. The Definitive manual, at least, mentions that it can pull files from DLNA servers. But I think they're talking about the 'generic' DTS Play-Fi app, i.e., I don't think they make their own app.
