Not necessarily. Can’t find the paper now, but a team which analyzed nationwide temperature measurement stations found that stations with good placement (that is, not placed right next to an air conditioning unit, or next to a runway, or somewhere else where external heat sources messed with the measurements) experienced considerably increases in daily minimums, but only minute differences in daily maximums; a trend which produces a higher average relative to the maximum than might be expected.
Your post is establishing Z, actually, a largely unrelated temperature phenomenon—maximum temperature. Hence my second paragraph.
Average temperature is relevant in this context, as average temp goes up we should expect the maximum to go up as well.
