I also have a V35 (also running Android 10) that plays all my DSD files just fine via LG's own music player and via UAPP.
Well then LG V35 seems to be the only odd exception supporting DSD/DoP over Android 10. Please note V35 is a very rare device with very limited regional availability.
LG G6, G7, G8, G8X, V30, V35, V40, V50 all came powered with same ESS ES9218P SABRE audio chip better known as LG QuadDAC.
The very next iteration of V35, the V40 dropped DSD/DoP support after Android 10 update. Why V35 didn't is very strange to me but at the same time is a welcome news to audio lovers.
(BTW, the DACs are different - the V60 uses the ES9219 chip.)
Yeah, V60 has this ESS ES9219, but I do NOT consider it to be an upgrade over ES9218P.
V60 Cons:
More than double the output impedance of the V35.
I think the measured output impedance of headphone jack has more to do with audio tuning house in question rather than hardware. Long time back I went to a Korean website, I don't remember the name now and they were using very high end gear to objectively measure the headphone audio performance of LG QuadDAC model's. I just stored some measurements numbers from there in my Cloud.
The audio measurement gear in question was Audio Precision APX-555. Below are their measured headphone output impedences (lower is better):
2017
------
LG G6 -> ES9218P -> 1.57 ohms
LG V30 -> ES9218P -> 1.10 ohms
2018
-------
LG G7 -> ES9218P -> 1.10 ohms
LG V40 -> ES9218P -> 1.60 ohms
2019
------
LG G8 -> ES9218P -> 1.07 ohms
LG V50 -> ES9218P -> 1.64 ohms
LG G8X -> ES9218P -> 1.55 ohms
First, Bang & Olufsen (B&O) tuned the ES9218P on G6 and improved it further on V30 with an output impedence of 1.10. Then B&O left and LG continued with G7 keeping the high standards.
Meridian Audio then joined and tuned V40 and it fell down to 1.60. This around 1.60 ohms traditon continued with other two models V50 & G8X tuned by Meridian. I highly doubt G8's QuadDAC was tuned by Meridian (just click the link below and you won't found G8) and was rather tuned by LG just like G7, hence a similar value of 1.07.

All models under 32 ohms load produced around 0.4 Vrms, under line out around 1 Vrms and with 300 ohms load around 2 Vrms.
In the end the values are authentic from the website, but the reasoning is hypothetical from my side, so I may be wrong.
