Par,unless I have misunderstood Kal's interesting intervention,you are incorrect to say there is no such thing as PCM multichannel from a SACD. I was always suprised that Kal never tried out the DA5400ES AVR which is the natural partner for the XA5400ES to evaluate digital mch. I believe he dislikes receivers preferring pre- pros which are of no interest to me. I hope Kal gets a Marantz SA-10 for a Stereophile review.

Not quite. There is no such thing as PCM multichannel from SACD*. However some players like yours can convert the DSD stream from the SACD DSD layer to PCM. This is what appears to have been happening for you in the past.
According to Kal the player needs to have a handshake with the receiver so that it knows that the receiver is capable of handling DSD data. Once it knows this then it stops converting and sends DSD via HDMI to the receiver. I would guess from your postings that when you reconfigured the settings you unknowingly sent the handshake code. Thereon the player stopped converting DSD to PCM and you had a full DSD experience.
* The CD ( PCM) layer of an SACD disc is redbook standard. Redbook has no provision for multi channel. If there was such a thing as a redbook protocol for multichannel then the disc playing time would be very short on a 12cm disc due to its data capacity in this format.
Too few channels.
