Yes. And I suspect due to its low temperature resistance (this an intuitive guess; I'm not exactly a materials science engineer) it also exhibits very poor cold creep/permanent deflection characteristics. ABS is actually the best of the bunch there, probably hand in hand with ASA.
However, one thing people are often surprised to learn or discover about boring old PLA is that it actually has among the highest layer adhesion strength of the commonly available materials, I believe second only to polycarbonate, and it's also the most rigid of the commonly available (non-filled) materials. At least at room temperature, anyway. It turns out that printing the screws for e.g. my Rockhopper or Adélie in anything but PLA amounts to being a fool's errand.
It's tempting to think of the litany of plastics available in filament form to consumers as a simple linear and escalating spectrum with "cheap, flimsy, easy to print" and one end and "expensive, strong, difficult to print" at the other. In reality as you know it's not quite so simple. If anything, the hypothetical graph describing the properties of PLA, PETG, PET, ABS, ASA, Nylon, polycarbonate, etc. would have to be three dimensional.
All makes sense, of course. If I want a “pretty” non-structural print PLA is always a top choice. Fine, smooth, easily bonded with CA glue. ABS is a lot more finicky, but strong.
