I am pretty sure you are correct.
Although I am not too positive that future histories of philosophy will look at this the same way, there was a major movement of thought in Germany and Austria that appropriated the "rightist", more conservative readings of Hegel (which are closer to his own thought IMHO). This appropriation can be summarised with two concepts:
- The historicised a priori (most explicit in Dilthey and much later Foucault)
- The hermeneutical (or anthropological) circle (most explicit in Plessner, Wittgenstein, and Heidegger as well as later Gadamer)
This started in the late 19th century with Wilhelm Dilthey, continuing with many thinkers who conversed with one another and, together with the classical pragmatists and their heirs as well as Russel and the positivists, changed philosophical thinking forever.
Basically, it makes clear that not only thought but the whole being of a person is tied to a social and cultural environment, a Lebenswelt, that this person cannot escape. This is antithetic to the Hegelian project that while allowing for different embodiments of truth, still argued for the absolute Geist being eternal and unchanging, yet accessible.
Ultimately, the point of all of those thinkers is that you can only think and be within your human being (which already means a particular access to the world) and your particular upbringing (which is a bit more palatable), both of which you can never fully transcend.
