Same here, no matches for 'wlan.vht.op.channelwidth != 1', only 1.

But Wireshark describes this value as
	Channel Width: 80 MHz, 160 MHz or 80+80 MHz BSS Bandwidth (1)

which I read as "supports these three modes/widths.

Again, the AP itself does report one device using 160 MHz and some
WiFi Analyzer app also tells me my SSID supports it.

FWIW, here's iperf3 client (IPv6, TCP, one thread, 10s) on AP against
servers on devices, i.e. no hop/router between them.

Speed varies and immediately successive runs usually yield higher values
until it maxes out, e.g. "Notebook" averaged around 250, 270, 300, 280
and 320 Mbits/sec in that order;  results below are absoloute maxima:
