Yes. Most likely in a wind tunnel with smoke. What you will see is highly dependent on Angle of Attack.
Ideally, any turbulence (that would be felt as buffet) is well away from the trailing edge. What should be seen at AoA below stall angle, aft of the wing, is a strong downwash from the upper wing combining with the deflected airflow from the lower wing.
Air deflected upwards by the top of the wing is pulled down and accelerated by low pressure near the wing surface (just as the wing is being pulled up). When AoA exceeds the stall limit, then downwash is insufficient and higher pressure "spills" over onto the top of the wing in the form of turbulence and vorticies, but this does not happen at lower AoA.
The trailing edge airflow pattern at lower AoA would be more like a "sheet" of downwash/upwash/downwash before it dissipates.
It is the downwash sheet energy that actually strengthens wingtip vorticies into the dangerous "tornadoes" that following aircraft may encounter.
