That is most definitely the case. If Black did not have the pawns on b7 and d6
the World could swiftly force a variety of draws.

An example is the so-called Endgame G:

47. Kf5   Nh8
48. g6    d2
49. g7    d1Q
50. Rxd1  Kxd1
51. gxh8Q b1Q

7Q/1p4P/3p4/5K2/8/8/8/1q1k4 w

If the Black pawns were absent, we would have

7Q/7P/8/5K2/8/8/8/1q1k4 w

which is a tablebased draw.

However, all the current analysis by the World Team suggests that with the two
pawns on Endgame G is almost certainly lost for Black. The current main line is

52. Ke6   Qe4+
53. Kd7   Qa4+
54. Kc7   d5
55. Qg7!  Qc6+
56. Kd8   Qb6+
57. Kc8!  Qc6+
58. Qc7!  Qf6
59. Qd7!  Qh8+
60. Kxb7  Qb2+
61. Kc6   Qh8
62. Qxd5

and we're back in the tablebase, but this time it's a win for White...

47. ... b1Q takes us to a ending with an advanced White g-pawn rather than
h-pawn, which currently seems to offer much better drawing chances, but again it
would be much easier if neither Black pawn was on the board! (c:

7Q/1p6/3p2K1/6P1/8/8/8/1k1q4 w
