blu-ray coaxial outputs limited rez to dacs?

I have not been here so long I forgot my login!  Anyway, is it impossible to get the hi rez audio from a typical blu ray on the coaxial audio output?  Got ahold of a Pure Audio blu ray disc of music.  Supposed to be 24/96 format.  My player is putting out only 16/48 into the dac according to the dac display.  So I went into player menu and made sure the "downsampling"  selection was in the off position.  Still, only the lower rez data showing up into the dac.  So does that mean I would need a mega bucks blu ray to get the actual hi rez or what?  The dac oversamples it up before decoding but is supposed to be happy to accept stuff up to 192/24 I think.

OK I will rephrase my question.  IS there a blu ray player that will output to a DAC with the full 24/96 from the Pure Audio discs?  That is not something in the mega bucks price range?   I messed with the settings on the player I have and still cannot get it.  It might be full rez on the HDMI to the TV or such, but I also would not like to invest in another box between the player and the DAC.  That is getting out of hand, for me.

Can someone please confirm and comment on the following:

"All blue ray players will play standard resolution (44.1 or 48 kHz) music over digital outputs. It is only high-resolution recordings (88.2 / 96 / 176.4 / 192 or DSD) with copy protection that will be downsampled for playback over digital output.

Due to bandwidth limitations, high resolution audio formats such as Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution and DTS-HDMaster Audio cannot be sent through the coaxial or optical digital audio output. A reduced resolution version of the same audio track will be output instead. To listen to high resolution audio formats in their best quality, please use the HDMI connection if you have a receiver that handles HDMI audio or use the multi-channel analog outputs if you do not.

Due to copyright restrictions, SACD audio cannot be sent through the coaxial or optical digital audio output. To listen to SACD, please use the HDMI or analog audio connections.

An examination of the digital outputs on DVD and Blu-ray players will show that the digital outputs are dumbed down to sample rates of 44.1 or 48 kHz at a bit-depth of 16 bits. These digital outputs are also limited to 2 channel PCM or lossy compressed 5.1 formats. No high-resolution audio is available at the digital outputs on any currently-available player".

That doesn't make sense really, as you can send GHz. microwave signals thru coaxial cable,  the amplitude losses from long runs being the only negative factor, usually.  But if it is how it is, so be it.   Maybe I will soon be selling a bluray disc cheap.  I did not see anything in the specs of the player that would indicate that restriction but it may be a standard.  Was hoping for finally a convenient hi rez  format with gear I already have.
