That's true for x264, so anything that uses x264 will only use rc-lookahead if mbtree is used.
iirc some older x264 version did write the configured rc-lookahead setting into the sei-block (<-this is what MediaInfo shows), even when it was not used. But for quite some time x264 wrote 0 in the sei-info when rc-lookahead wasn't used.
