There were three Venetian painters named Bellini. Jacopo (c. 1400-1470/1) was the father. Gentile Bellini (c. 1429-1507) is said to be his elder son, and Giovanni Bellini (c. 1431 - 1516) his younger son. Normally a reference to Bellini without qualification refers to Giovanni.
It is certainly the case that Giovanni Bellini made use of renaissance features in his painting, not least as in the San Zaccaria altarpiece, to relate to its setting within the church. However, it is not true of Giovanni Bellini's Pietà; in the gallery of the Academy of Venice.
It is clearly not true that Gentile Bellini confined himself to renaissance styles of architecture, as Ruskin points out at MP I:106 in writing of Procession in the Piazza San Marco, nor is it true of his Miracle of the True Cross at the Bridge of San Lorenzo, both in the gallery of the Academy of Venice. The Procession in the Piazza San Marco is discussed in Ruskin's Guide to the Academy at Venice, and illustrated in the p. facing Works, 24.164.
Ruskin gives a further example at Works, 9.325 of the architectural painting of Gentile Bellini and also of Carpaccio. Ruskin remarks at Works, 11.27 on the evidence of Gentile Bellini about the fresco colouring of the Gothic palaces, something which Canaletto is disparaged for not doing, and which is discussed in relation to the work of Veronese, and of Giorgione and Titian on the frescoes of the Fondaco dei Tedeschi.
