Not quite the same, but Cloudflare's statistics show that 8.1% of all DNS requests to its public resolver are for HTTPS RRs [0], and the statistics on the authoritative DNS server that I run [1] show that only 1.11% of requests were for an HTTPS RR.
A1: it’s naive to assume we’re at 100% https:// adoption? Any http:// URL will not trigger an HTTPS DNS lookup.
A2: site popularity and downstream caching of 1.1.1.1 means CloudFlare see fewer requests for HTTPS DNS than there are https:// connections?
