Pretty much.
Apple has loyal user base as well as the best integration within their own ecosystem which highly satisfy the needs of the majority of its users. They also contributed to development of AAC as well as made one of the best implementation of the codec (consider how Apple can achieve almost no latency with its AAC implementation that's pretty much universally usable on old and new hardware alike, whereas Qualcomm requires you to buy aptX LL compatible equipment etc), therefore there's no need to use aptX/LDAC in their products. If you can already make everything inhouse and your customer based is loyal to your products then why pay money to someone else? Considering that Apple sells tens if not hundreds of millions of iOS products each quarter, even if it is just a dollar of licensing fee that's several millions of dollars to a competitor as well as strengthening the competitors' market position over itself, so it is absolutely not in Apple's interest to license LDAC or aptX.
There is also what could be called Sony Marketing Mysteries. Like Native DSD was only allowed to port 4.4mm on the 1A and 1Z yet now with MrWalkman DMP-Z1 the Native DSD is ported to 3.5mm single ended. Which doesn’t sound like much unless your life revolves around using the Walkmans to a speaker power amp or external headphone amp, then the pieces start to fall in place. Note 4.4mm balanced is not used 4.4mm to 2X RCA. Also it gives a note to wonder in AAC implementation inside the Walkman is stifled too?! Being AAC ends a competition codec?
Edit:
It’s like balanced is not necessarily better though as Sony we will push Pentaconn so make the Pentaconn side amp better, also disable Native DSD non-Pantaconn.
